For every prophet faithfully communicating the word of YHWH to Israel, many others claimed to have contradictory messages from YHWH which He had not spoken. The messages of the latter appealed to the people.
As Israel was beset by the false prophets, so the church was beset by false teachers. They also spoke messages which appealed to the people.
We do well to consider from Scripture what is revealed about the false prophets and teachers lest we fall according to the same pattern of disobedience!
